Antibiotics with promise — a lifeline India awaits


From UPSC perspective, the following things are important :

Prelims level: AMR and EUA

Mains level: India's innovative mechanism for antibiotics

Central Idea

  • The battle against highly drug-resistant infections has reached a critical stage, where the need for effective antibiotics cannot be overstated. In a recent incident, a team of doctors encountered a challenging situation that showcased the critical importance of taking immediate action.

Relevance of the topic

Relate it with the antimicrobial resistance (AMR). AMR often also called antibiotic resistance, is a global health challenge and a looming public health crisis.

The Case of Extensively Drug Resistant Pseudomonas aeruginosa

  • In an intensive care room, a brave 18-year-old patient fought not only T-cell leukemia but also an aggressive and resistant strain of Pseudomonas aeruginosa.
  • With limited treatment options due to the bacterium’s high resistance to antibiotics, the patient’s condition deteriorated rapidly.
  • The infection attacked his lungs, resulting in persisting fever spikes and severe damage to his face. Time was running out, and his life hung in the balance.

Indian Innovation in antibiotic development

  • Effective Combination: Cefepime/zidebactam is an innovative antibiotic developed by Indian researchers. It combines two active components to combat drug-resistant gram-negative pathogens, including the formidable Pseudomonas aeruginosa.
  • Promising Results: This Indian innovation has shown remarkable potential in combating highly drug-resistant infections. It has undergone phase 3 trials internationally, demonstrating its effectiveness and safety profile.
  • Compassionate Use: In a compelling case, an 18-year-old patient suffering from T-cell leukemia and an extensively drug-resistant strain of Pseudomonas aeruginosa experienced a miraculous recovery after receiving cefepime/zidebactam under a compassionate use protocol. This highlights the life-saving impact of this innovative antibiotic.
  • Urgent Need for EUA: The extraordinary case of the patient’s recovery emphasizes the urgent need for Emergency Use Authorization (EUA) for antibiotics like cefepime/zidebactam that have shown promising results in phase 3 trials or have been licensed from other countries. Granting EUA would enable timely access to this effective treatment option.
  • Strengthening the Arsenal: By recognizing the importance of cefepime/zidebactam and expediting its EUA, India can strengthen its arsenal against drug-resistant infections. This Indian innovation can contribute significantly to addressing the global challenge of drug resistance.
  • Potential Global Impact: Granting EUA for cefepime/zidebactam not only saves lives within India but also extends a helping hand globally to countless individuals in desperate need of effective treatment options. India’s scientific achievements can make a substantial impact on the world stage.
  • Scientific Prowess: Cefepime/zidebactam stands as a shining example of India’s scientific prowess in the field of antibiotic development. It showcases the nation’s ability to innovate and provide solutions to combat drug-resistant infections.

The Dire Situation and the Devastating Reality

  • Scarcity of Potent Antibiotics: The dire situation arises from the scarcity of potent antibiotics to combat highly drug-resistant infections. The available antibiotics have lost their effectiveness due to rising resistance, leaving healthcare professionals with limited treatment options.
  • Lives at Risk: The devastating reality is that countless lives are at risk due to inadequate antibiotics. Patients, particularly those who are critically ill or immunocompromised, are succumbing to infections that were once treatable. This results in significant morbidity and mortality rates.
  • Ineffectiveness of Current Antibiotics: Rising drug resistance has rendered once-effective antibiotics ineffective against formidable pathogens. The constant evolution and mutation of bacteria pose a significant challenge to doctors in providing effective treatment.
  • Multifaceted Challenges: Doctors face multifaceted challenges in combating drug-resistant infections. They must navigate through a shrinking arsenal of effective antibiotics, leading to limited choices and the use of suboptimal treatments. This situation adds immense pressure and helplessness to doctors on the front lines.
  • High Death Toll: The dire situation and devastating reality contribute to a high death toll attributed to drug-resistant infections. Millions of lives are lost each year due to the inadequacy of available antibiotics in effectively treating these formidable pathogens.
  • Race Against Time: Healthcare professionals are constantly racing against time, trying to stay one step ahead of mutating bacteria. The urgency to find effective solutions and the frustration of not having access to life-saving antibiotics in critical situations weigh heavily on doctors.
  • Global Concern: The dire situation and devastating reality of drug-resistant infections are a global concern. It requires collaborative efforts from healthcare authorities, policymakers, researchers, and pharmaceutical companies to address the challenge and develop effective solutions.

What is Emergency Use Authorization (EUA)?

  • EUA is a regulatory pathway that allows for the expedited authorization and use of medical products during public health emergencies.
  • Under EUA, medical products, including vaccines, therapeutics, and diagnostics, can be made available for use in emergency situations before they receive full approval or licensure. This allows for a more rapid response to public health crises, such as outbreaks or pandemics, by providing access to potentially life-saving interventions.
  • EUA involves a rigorous evaluation process by regulatory authorities, who assess the available scientific evidence, safety data, and potential benefits and risks of the medical product.

The Urgent Need for EUA

  • Limited Treatment Options: In the face of highly drug-resistant infections, the available treatment options become limited and often ineffective. Conventional antibiotics may not be effective against these infections, leading to prolonged illness and increased mortality rates.
  • Life-Threatening Infections: Drug-resistant infections can pose significant risks to patients’ lives, especially those who are immunocompromised or critically ill. Immediate access to effective treatments is crucial to combat these infections and improve patient outcomes.
  • Time-Sensitive Situations: In some cases, time is of the essence, and delays in accessing effective treatments can have severe consequences. EUA allows for expedited authorization and access to potentially life-saving interventions in emergency situations.
  • Addressing Public Health Emergencies: EUA plays a crucial role in responding to public health emergencies, such as outbreaks or pandemics, where swift action is needed to deploy interventions that can save lives and mitigate the spread of infections.
  • Balancing Safety and Efficacy: While EUA expedites access to treatments, safety and efficacy remain critical considerations. Rigorous evaluation and monitoring are essential to ensure that authorized treatments meet the necessary standards for patient safety and effectiveness.
  • Supporting Research and Development: EUA can provide a pathway for essential treatments that are still in clinical trials to be made available to patients who have no other viable options. This allows for the collection of real-world data and insights that can further inform research and development efforts.
  • Global Collaboration: EUA for essential treatments can also enable collaboration and sharing of knowledge and resources on a global scale. It allows countries to work together in addressing public health challenges and ensures equitable access to life-saving interventions.


  • The story of the 18-year-old patient’s recovery highlights the critical need for Emergency Use Authorization for essential antibiotics. The scarcity of potent antibiotics and the rising threat of drug-resistant infections demand urgent action. By granting EUA for promising antibiotics like cefepime/zidebactam and cefiderocol, we can save lives and make a significant impact globally. It is time for India to demonstrate its scientific prowess and commitment to combatting the challenges posed by drug-resistant infections
